《易》曰∶干道成男，坤道成女。干刚用事，得阳气之专者，则多男；坤柔用事，得阴
事之全者则多女，此定理也。男子平时，清心寡欲，养其干健之体，则所感而生男矣。至于
受胎时日之法，谓断经一、二日，感者成男，三、四、五日，感者成女。诚以一、二日间阴
气方亏，则阳气当胜，故生男。三、四、五日，阴血既回，则阳气不胜，故生女。此乾坤之
性情，刚柔之体用也。今方家备载转女为男之法，有束皮革者，有佩雄黄者，有暗藏雄鸡羽
于席下者，有暗藏斧于床下，而系刃向下者，种种诸法，或验或不验。其验者，安知其非幸
中耶？终不若讲究本原为合理也。
经谓妇人有孕者，身有病而无邪脉也。有病，谓经闭。无邪脉，谓脉息如常，不断绝也
经又云∶手少阴脉动甚者，孕子也。少阴，心也，心主血脉，心脉旺则血旺，而为孕子之
兆。经又云∶阴搏阳别，谓之有子。言二尺脉旺，与两寸迥别，亦为有孕。以上三者，但得
其一，即为孕脉。分而占之，合而推之，而孕脉无遁情矣。或谓流利雀啄，亦为孕脉，何也
？答曰∶流利者，血正旺；雀啄者，经脉闭塞不行，故脉疾而歇至，此数月之胎也。不知者
断为病脉，则令人耻笑。或谓∶孕有男女，何以脉而知之也？答曰∶左寸为太阳，脉浮大，
知为男也。右寸为太阴，脉沉实，知为女也。若两寸皆浮大，主生二男。两寸皆沉实，主生
二女。凡孕脉，弦紧滑利为顺，沉细微弱为逆也。

《易经》说：天道成就男性，地道成就女性。乾刚发挥作用，得到阳气纯正的，则多生男孩；坤柔发挥作用，得到阴气完整的，则多生女孩，这是确定的道理。男子平时，清心寡欲，保养其刚健的身体，那么所感受而生下的就是男孩。至于受孕时日的方法，说断经一、二天，受孕的成男孩，三、四、五天，受孕的成女孩。确实因为一、二天之间阴气方才亏损，那么阳气应当占胜，所以生男孩。三、四、五天，阴血已经恢复，那么阳气不能占胜，所以生女孩。这是乾坤的性情，刚柔的体用关系。现在医家详细记载转女为男的方法，有用皮革束身的，有佩戴雄黄的，有暗中在席子下藏雄鸡羽毛的，有暗中在床下藏斧头而让刃口向下的，种种各种方法，有的灵验有的不灵验。那些灵验的，怎么知道不是侥幸中的呢？终究不如讲究根本原因为合理。
经文说妇女怀孕的，身体有病象但没有邪脉。有病，指月经闭止。无邪脉，指脉搏像平常一样，没有断绝。经文又说：手少阴脉跳动明显的，是怀孕。少阴，指心脏，心主血脉，心脉旺盛则血旺，成为怀孕的征兆。经文又说：尺部阴脉搏动有力，与寸部阳脉截然不同，叫做有孕。说的是两尺脉旺盛，与两寸脉迥然不同，也是怀孕的迹象。以上三种情况，只要具备其中一种，就是孕脉。分别占测它，综合推究它，那么孕脉就没有隐瞒的情况了。有人说流利如雀啄，也是孕脉，为什么呢？回答说：流利的，是血正旺盛；雀啄的，是经脉闭塞不通，所以脉疾速而有间歇，这是几个月的胎。不懂的人断定为病脉，就会令人耻笑。有人说：怀孕有男女，凭什么通过脉象来知道呢？回答说：左寸为太阳，脉浮大，知道是男孩。右寸为太阴，脉沉实，知道是女孩。如果两寸都浮大，主生两个男孩。两寸都沉实，主生两个女孩。凡是孕脉，弦紧滑利为顺，沉细微弱为逆。

The *Book of Changes* states: The way of Heaven forms males, the way of Earth forms females. When the firmness of Heaven is in operation, one who obtains the purity of Yang Qi will have more sons; when the softness of Earth is in operation, one who obtains the completeness of Yin will have more daughters. This is a fixed principle. For men, maintaining a pure mind and few desires, and nurturing their vigorous constitution, results in conceiving sons. Regarding the method for determining conception time based on days after menstruation ceases: conception occurring one or two days after cessation leads to a male child, while conception occurring three, four, or five days later leads to a female child. Indeed, during the first one or two days, Yin Qi is just depleted, so Yang Qi prevails, thus producing a male. During three to five days, Yin Blood has returned, so Yang Qi does not prevail, thus producing a female. This reflects the nature of Heaven and Earth, and the substance and function of Firmness and Softness. Currently, medical practitioners record various methods for changing a female fetus to a male, such as binding with leather, wearing Realgar, secretly hiding rooster feathers under the mat, or secretly hiding an axe under the bed with the blade facing down. These various methods are sometimes effective and sometimes not. For those that are effective, how can we know they are not merely lucky coincidences? Ultimately, it is more reasonable to focus on understanding the fundamental origin.
The Classics state that for pregnant women, there are symptoms of illness but no pathogenic pulse. "Symptoms of illness" refers to amenorrhea. "No pathogenic pulse" means the pulse remains normal without interruption. The Classics also say: If the pulse at the Hand Shaoyin position beats strongly, it indicates pregnancy. Shaoyin refers to the Heart, which governs blood vessels. When the Heart pulse is vigorous, blood is abundant, serving as a sign of pregnancy. The Classics further state: "Yin pulses beat strongly, distinct from Yang," which signifies pregnancy. This means the pulses at both Chi positions (尺部) are vigorous and markedly different from the pulses at both Cun positions (寸部), which also indicates pregnancy. Among the above three signs, possessing any one constitutes a pregnancy pulse. Analyzing them separately and synthesizing them comprehensively leaves no room for concealment regarding pregnancy pulses. Some ask: Why are smooth and sparrow-pecking pulses also considered pregnancy pulses? The answer is: Smoothness indicates abundant blood; sparrow-pecking indicates obstruction of meridians and collaterals, causing the pulse to be rapid with intermittent pauses, which occurs several months into pregnancy. Those unaware may mistakenly diagnose this as a pathological pulse, which would be laughable. Others ask: How can one distinguish between male and female fetuses via pulse diagnosis? The answer is: The left Cun position corresponds to Taiyang; if the pulse is floating and large, it indicates a male fetus. The right Cun position corresponds to Taiyin; if the pulse is deep and solid, it indicates a female fetus. If both Cun positions are floating and large, it suggests twins of male gender. If both Cun positions are deep and solid, it suggests twins of female gender. Generally, for pregnancy pulses, wiry, tight, slippery, and smooth characteristics are favorable (Shun), while deep, fine, weak, and thready characteristics are unfavorable (Ni).
